INDICATOR OR BULLETIN.

To all whom it may concern:

Be it known that I, NED E. BARNES, a citizen of the United States,residing at Willis, in the county of Montgomery and State of Texas, haveinvented certain new and useful Improvements in Indicators or Bulletins;and I do hereby declare the following tobe a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to new and useful improvements in indicators orbulletins and more particularly to that class adapted to be used instreet cars or railway coaches and my object is to provide a belt, uponwhich are placed the objects to be exhibited, which may consist of anysuitable form of advertising the stations or street crossings or ifpreferred, the two may be combined.

A further object is to provide shafts, upon which said belt is to bewound.

A further object is to provide a housing for the belt and shafts andplace therein an opening, in registration with which the printed matterupon the belt is adapted to be moved.

A further object is to provide means whereby either of said shafts maybe rotated, and, a further object is to provide means for limiting therotation of said shafts, whereby the movement of the belt will bestopped at the proper position to exhibit the printed matter thereon.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the specification and claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a front elevation of the indicator. Fig. 2 is an endelevation thereof. Fig. 3 is an end elevation of the opposite end of theindicator, and, F at is a transverse sectional view through theindicator.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates a housing,which may be constructed in the usual or any preferred manner, in thefront wall of which is provided an opening 2 and over said opening ispreferably positioned a glass 3 or any suitable transparent material.Extending longitudinally through the housing and beyond each end thereofare shafts at and 5,

l upon which a belt 6 is adapted to be wound, I

one end of the belt being fastened to the shaft 4 and the opposite endto the shaft 5. Guide rollers 7 are placed above and below the opening2, around which the belt extends, so as to position the belt adjacentthe opening 2 in the housing, whereby the printed matter on the belt maybe readily observed through the opening. If the belt is being wound uponthe shaft 4, a lever 8 is mounted upon one end of the shaft 4, the endof the lever engaging the shaft being bifurcated to receive a ratchetwheel 9 with which cooperates a pawl 10 carried by the lever. The lever8 is rotatably mounted upon the shaft, while the ratchet wheel 9 isfixed thereto by extending a tongue 11 into a groove 12 in the shaft andit will be readily seen that when the lever is moved upwardly, the shaft4 will be rotated and the belt wound thereon, while the pawl will freelyride over the ratchet when the lever is swung in the opposite direction.The free end of the lever is swung downwardly through the medium of acable 13, the free end of the cable being positioned in convenient reachso that a pull can be made upon the cable. As soon as the cable isreleased, the free end of the lever is swung upwardly and the shaft 4rotated by means of a spring 14, one end of which is attached to thelever and the opposite end to an eye 15 on the housing 1. The same endof the shaft 5 is also provided witha groove 16, which is adapted toreceive the tongue 11 of the ratchet wheel when the belt is to be woundupon the shaft 5 and when the lever and ratchet construction are engagedwith the shaft 5, the spring 14 is engaged with an eye 17. placed uponthe housing 1 at a point below the eye 15. The rotation of the shafts islimited, whereby the belt will be moved the proper distance each time todis play the printed matter placed thereon by means of a latch 18, oneend of which is pivoted to a stud 19, while the opposite end thereof isprovided with a detent 20, which engages notches 21 in the periphery ofa wheel 22. When the lever 8 is cooperating with the shaft 4, the wheel22 is engaged with the shaft 5 and in order to cause the wheel to rotatewith the shaft, said shaft is provided with a groove 23, with whichengages a tongue 24. on the wheel 22 and it will be readily seen thatwhen the tongue is engaged with the groove, said wheel cannotrespectively to said shafts, a lever and rotate independently of theshaft. The notches are placed a sufficient distance apart so as topermit the belt to travel the width of the opening in the casing, whilethe wheel is traveling the distance from one notch to the nextsucceeding notch, and when the wheel 22 has rotated a sufficientdistance to bring the next succeeding notch into registration with thedetent, said detent will descend into the notch and prevent furtherrotation of the shafts and belt.

Prior to giving a pull on the cable 13, the latch 18 is elevated out ofengagement with the wheel, which is accomplished by engaging one end ofa cable 25 with the latch and extending said cable over sheaves 26 andin convenient reach of the person operating the indicator. As soon asthe lever starts to rotate the shaft at, the latch is released andpermitted to descend so that the detent thereon will enter the nextsucceeding notch when moved into alinement with the detent.

If the belt is being wound upon the shaft 5, the wheel 22 is mountedupon the shaft at, which shaft is also provided with a groove 27 toreceive the tongue on said wheel and the stud 19 is so arranged that thelatch can be swung upwardly to cooperate with the wheel when placed onthe upper shaft.

By this construction, it will be readily seen that the belt can be movedfrom end to end to exhibit certain printed matter thereon and when thecar has reached the end of the route and starts in the oppositedirection, the belt can be wound in the opposite direction bytransferring the lever and stop mechanism from one shaft to the other.It will further be seen that the indicator can be readily mounted at anyconvenient point within the coach or car and conveniently operated bygiving a pull. to the cables depending from parts of the indicator, andit will likewise be seen that the movement of the belt in eitherdirection can be readily regulated and stopped at the proper place.

What I claim is 1. The herein described indicator, comprising a casing,shafts extending through said casing, a belt having its ends attachedratchet mechanism adapted to be attached to either of said shafts towind the belt thereon, a wheel having notches therein, said wheel beingadapted to be engaged with either of said shafts and a pivotally mountedlatch adapted to engage said notches and limit the rotating movement ofeither of the shafts to which the wheel is attached.

2. An indicator of the class described, comprising a casing having anopening therethrough, a pair of shafts extending longitudinally of thecasing and one above the other, a belt having its ends securedrespectively to said shafts, means to cause the belt to pass in closeproximity to said opening in the casing, a lever adapted to be placedupon either of said shaftsand swing thereon, a ratchet wheel adapted tobe mounted upon either of said shafts, means to cause the ratchet wheelto rotate with the shaft, a pawl on the lever adapted to operate theratchet wheel to rotate the shaft, means whereby a downward pull may begiven said lever, automatic means for elevating said lever and means atthe opposite end of the casing adapted to be engaged with either of saidshafts to limit the rotating movement of the shafts.

3. An indicator, comprising a pair of shafts, a b e lt adapted to bewound upon either of said shafts, means to rotate one of the shafts towind the belt thereon and a notched wheel adapted to engage either ofsaid shafts and rotate therewith, a latch pivoted to the housing andhaving a detentthereon adapted to engage said notches of the wheel whenthe wheel is on either shaft and means whereby said latch may be swungupwardly and disengaged from the when: when the wheel is in position oneither shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
